no encoding is not multithreaded - it would be somawhat more complicated
as you need previous images so using multiple threads makes this process
somewhat harder - so AddFrame will wait till image is encoded
and stored in the file buffer.

dropped frames usually means the encoded lenght is 0 - so
in that case you don't have to refresh image - and as I said there
is no multithreading in the encoding.
